The data below shows a Survey conducted by Frank on age (Years) of basic shop learner in OPRT. a. Use tallies to organise the data to frequency table. b. Draw a pie chart to illustrate the information. c. find the percentage of those who are more than eleven Years.

The ages given in the survey are:
$11, 10, 12, 14, 11, 11, 14, 10, 12$
$12, 11, 11, 11, 10, 14, 11, 10, 11$
There are 18 data points in total.

We count the occurrences of each age:

• Age 10: 4 times
• Age 11: 8 times
• Age 12: 3 times
• Age 14: 3 times

The frequency table is:

To draw a pie chart, we calculate the angle for each sector using the formula: $\text{Angle} = \frac{\text{Frequency}}{\text{Total Frequency}} \times 360^\circ$.

• For Age 10: $\frac{4}{18} \times 360^\circ = 80^\circ$
• For Age 11: $\frac{8}{18} \times 360^\circ = 160^\circ$
• For Age 12: $\frac{3}{18} \times 360^\circ = 60^\circ$
• For Age 14: $\frac{3}{18} \times 360^\circ = 60^\circ$ The sum of these angles is $80^\circ + 160^\circ + 60^\circ + 60^\circ = 360^\circ$. To draw the pie chart, you would draw a circle, then use a protractor to mark these angles from the center, creating sectors. Each sector should be labeled with its corresponding age.

"More than eleven years old" includes individuals aged 12 and 14.
Number of people aged $12 = 3$
Number of people aged $14 = 3$
Total number of people more than 11 years old = $3 + 3 = 6$.
Total number of people surveyed = 18.

The percentage is calculated as:
